'The nozzle 15 is formed and arran ed iiuid in the body so that the devicev is always so that fiuid, say, steam, under pressure` is- Vprimed and ready for operation, and means charging from l,the openings 18 effectively forces fluid into the body A. The discharge openings 18 are preferably small so that the fluid under pressure discharges from them at a high velocity.

rllhe means F provided for forcing the fluid from the body A and through the pipe 12 includes a nozzle 2O disposed in the opening 13 of the body. The nozzle 2O may be formed integral with the body and is preferably located just above the recess 14. 1n the form of the invention illustrated, the lower part of the nozzle 2O forms the upper wall of the recess 14. An opening 21 extends through the nozzle 2O from one end to the other. The nozzle 20 extends upwardly in the opening' 13 and discharges upwardly in the center of the opt-ming- 13. A tip 22 may be provided on the nozzle, for instance, screw Ythreaded into the opening 21 to extend upwardly to a point near the top of the body. The tip 22 discharges upwardly at a point centrally located in the discharge opening 11. It will be obvious that other forms of jets .or tips may be used instead of the openings 1Sandthe tip 22 without departing' from the spirit of the invention. The tip 22 is positionedso that itdischarges fluid under pressure at a point to effectively force fluid out through the conduit v12. The tip 22 discharges at .the reduced upiper endrportion of the opening` 13'so that the fluid is forced into the pipe 12 at a high rate of speed.

The manifold -M `delivers fluid under pressure vto thenozzles 15 and 20. 1n the form of the invention illustrated Vthe manifold M is located at one side lof the body A and is preferably at the side of the body having the recess14. T he manifold is preferably formed integral with the body and the back Wall of the recess 14 forms the inner wall of the manifold. Themanifold M is provided with an inlet opening 27 at its upper end, the opening .27 being threaded to receive the vsupply pipe 28. The pipe28-supplies steam or other fluid under pressure to the manifold M. rEhe manifold is divided into two branches, a branch 30 connected with-the nozzle 15 and a branch 31 connected with the nozzle 20. The branch 30 yextends `to the `lower fend of the body A. and registers vwith the passage 17 of the nozzle 15. rllhe branch31 extends directly into the nozzle 20, the two parts being formed integral. The manifold being formed in this manner, -there is but rone joint or connection between the supply pipe. 23 and the nozzles 15 and 20.

The means P, which automatically traps fluid inthe body A when the flow of fluid through the nozzles 15 and ,20 is stopped, keeps rvthe devicefprimed for the next opera tion.l Thisineans includes a valve 32 carried within the body, and a valve seat 33 inthe intake opening 1t). rlihe `valve seat 33 annular in form and is screw threaded into the opening 10. rllhe opening 34a in the seat adclosed.

mits fluid into the body. The top 34 of the seat 33 is flat and is finished to receive the valve The seat ring 33 may be provided with grooves or notches 35 in the wall of the opening 34aL so that it can be readily engaged by a wrench, or the like.

rhe valve 32 is pivotally mounted and is carried within the opening 13 of the body. An arm 36 projects laterally from the valve and is carried` by a pivot pin 37 held by a lug 38 on the wall of the opening 13. The valve 32 is mounted so that it is movable from a closed position where it is seated on the ring 33 to an open .position in the recess 14. The valve 32 is in the form of a round disc or V.plate and has a flat sealing face 39 on its lower side to cooperate with the face 34V of the seat ring. The top of the valve is provided with a stop 40 which may be screw threaded into the valve and which engages .the wall of the recess 14 to limit the opening movement of the valve. The valve is arranged so that the fluid discharged through the openings 18 Vholds it in the open position in the recess 14 and so that it Yautomatically returns to the closed position by flow of fluid downwardly in the body. The stop 40 holds the valve 32 in a tilted open position away from the wall of the recess 14 so that the fluid flowing downwardly inthe body A catches it and forces it rlhe head of fluid in the body and conduit 12 holds the valve closed when the device is not in use. The valve 32.1nay be counterbalanced so kthat it iseasily operated to the open position. 1n the drawings 1 have shown a coil spring 41 extending between the top of the valve 32 and the wall of the recess 14 to counterbalance the weight of the valve.

y1`he means G, provided to prevent solid matter or foreign material from entering the body ofthe ejector, consists of a plurality of Vstrainer fingers or guards43 arranged around the discharge openings 18 of the lifting nozzle. The guards 43 are provided to strain the fluid that enters the opening 34a so that pieces of solid matter' large enough to become caught in the device or tointerfere with the functioning of the device cannot enter the body rlhe guards 43 project upwardly from the top 44 of the nozzle 15 and are spaced short distance apart. The guards are symmetrically arranged around the openings 18 and extend upwardly. The .guards terminate close to the lower side of the seat ring The guards may be curved as shown in 2 of the drawings and may be spaced to allow fluid to freely pass between them, but to prevent any large pieces of foreign matter from passing between them.

ln operation fluid under pressure, preferably steam is passed through the supply pipe 28 and the manifold M and discharges through. Vthe openings 18 and the? tip 22. 'When the ejector is not operating, the valve 32 is normally closed and the body A is filled with fluid. The Huid or steam discharged through the openings 18 forces the valve open to the position shown in Fig. 1 of the drawings, and raises or lifts the fluid that is in thev body into the pipe 12. The steam discharg` ing through the tip 22 of the nozzle F forces the'liquid through the pipe 12.V The jet action of the steam discharging from the openings 18 draws fluid into the body throughthe opening 10. It will be apparent how the guards 43 strain the fluid as it enters the body and prevent large pieces of solid matter from entering the device.

The ejector provided by this invention is formed of a minimum number of parts and is inexpensive of manufacture. The manifold being formed integral with the body,

` makes the device compact and light. The upward convergence of the body causes the fluid passing through it to increase in speed so that it enters the pipe 12 at a very high velocity.

Having described only a typical, preferred form of my invention, I do not wish to limit myself to the specific details set forth, 'but wish -to reserve to myself any changes or variations that may appear to those skilled in the art or fall within the scope of the following claims.

4Having described my invention, I claimz'f 1. IA device of the character described includmg, a body having an inlet opening, a`

fluid pressure jet discharging at a pointbef low the body for lifting fluid into the body,

a iuid pressure jet discharging in the upper portion of the body for forcing fluid from the body. a -va-lve for automatically trapping p fluid in the body upon the discharge of Huid from the first-mentioned jet stopping and normally held open by the' fluid pressure from said jet, and a spring for counter-I balancing the valve.

2. A device ofthe character described, in-v cluding a body having a central longitudinal opening open at its lower end, a nozzle disf charging upwardly into the lower end of the body opening from a point spaced below the lower end of the body for lifting fluid into the body, jet means in the body for forcing fluid from the body, guards projecting upwardly from the discharge of the nozzle to a point adjacent the lower end of the body, and a valve for automatically trapping fluid in the body upon the discharge of fluid from the nozzle stopping.

In Witness that I claim vthe foregoing I have hereunto subscribed my name this 13th day of May, 1929.
